What Is Ember?
Netflix, Microsoft, LinkedIn, TED, Twitch are some of the popular apps built with ember.
What Is Svelte?
Unique quality of Svelte is the addition of first-class support of reactivity. This allows for improved performance without need for a Virtual Dom, which makes Svelte’s rendering fastest of any JS framework. Component-based and lightweight, Svelte is written in TypeScript. But the framework doesn’t need the knowledge of Typescript to use it.
TeamSpeak, Houses Of World, Doka by PQINA, Tableplop are some of the popular apps developed with Svelte.

Ember Vs Svelte- A Comparison
1. Learning curve-
This framework has a steep learning curve. The MVC pattern is not difficult to learn and understand but it follows a complicated standardized pattern of adopting functions and tools. At the initial stages, someone might find it challenging to learn. The current documentation of Ember is not bad but it is not to the mark of making it easy for beginners.
The older version of Ember follows the MVC architecture pattern. Let’s have a look at MVC.
Model: It provides the objects and elements of the app to wrap database records very quickly.
View: This component of Ember functions as a Ember template which makes use of templating language like Handlebars. This way of structure allows Ember to easily inject data into the view part of an application dynamically.
Controller: In contrast to most frameworks, in Ember, the route handlers deal with the controller tasks, like, getting the data and passing to the view components.
The new version of Ember works with the architecture of component-service and in some cases to provide asynchronous functioning and handle multiple processes simultaneously.
It is a server-side rendering focused framework, which provides tools, plugins, external dependencies needed to build a complex or an advanced application in a feasible manner. Now ember follows the MVC pattern and extends framework by allowing components to access the DDAU functionality pattern and this makes it good to build large-scale apps.
It is not at the stage of building complicated web applications. Svelte builds cybernetically enhanced applications. Other frameworks have the record of dealing with input blocking events, but Svelte hasn’t proved perfect in a particular domain.
Performance is the important factor for not only large projects but also for small projects too. And it becomes most important while building complex and large projects. So let’s compare Ember and Svelte in terms of performance.
It is a heavyweight framework known for its complicated tools and components which is generally preferred to build large-scale applications. This complexity eases the handling of advanced functions of application, but it lags when the application is launched. This takes a couple of moments before it can start running smoothly. However, the performance of Ember is high. The two-way binding and server side rendering features of Ember provide the possibility to work as a Glimmer rendering engine. Accordingly, it can build rapid rendering speeds.
From the developer’s perspective, Svelte is a well-optimized framework. It offers a great flexibility to produce high-quality code that performs well. It optimizes the user code at compile time, this implies applications have least runtime overhead-taking the users to have the more benefit of super-fast loading and UI navigation. There are many opportunities where Svelte makes inexpensive efforts to bring app performance than other frameworks. This framework reduces the overhead without dealing with the optimizations related to Virtual DOM, which means Svelte offers great performance without falling into the complexity of Virtual DOM overhead and concurrent modes.
It provides a wide range of tools to build scalable apps. It’s MVVM architecture can provide flexibility without compromising the code composability feature. This provides the ability to render huge data codes with high performance at the same time. Simply, it supports scalability that also good for developing large scale applications or extending an existing application.
It is not the best solution to build scalable applications. However, since it can be used related to other frameworks, there are speculations that it can contribute to building scalable and reusable components.
It allows developers to write tests in a way that can help fast and automatic refactoring code faster and easier. In simple words, manual testing is not much needed with Ember. It offers tools for testing, some of these are Qunit, Qunit DOM, Mocha, Chai DOM. Ember’s best feature is that the CLI suggests the type of testing that you should undertake based on the setup of the application program.
Svelte is more about contributing small size libraries and less complicated computations. You can write more testable code in Svelte than any other front-end frameworks because the frontend is about how users feel and interact with your web app. This framework is more business-friendly by generating testable code. It pushes the plan to compose unit tests and offers a Svelte testing library, a lightweight solution for testing Svelte components.
It follows security precautions by the regulations practices set by cross-site request forgery tokens.These CSRF practices ensure that Ember apps can be protected against attacks like cross-site scripting, content-security attacks. Ember has a severe Security Policy set up that helps the application’s handlebars to automatically prevent attacks like XSS.
Till today, there is no listed prerequisites in the official Svelte document regarding security updates and guidelines.
8. Application size-
With ember, building a large scale application or complicated enterprise app needs advanced tools, elements and libraries. At the point when all the necessary components are used, Ember turns out to be more prominent in size than you might expect. You can reduce the app size by choosing the right tools and still the core bundle of app might remain large despite any removal of adjustments made with external libraries and tools used. Simple app built Ember v1.0 turns out to be 272kB size. But for larger projects, this fact is neglected considering the high performance and rich UI Ember can offer.
When To Choose Ember?
- Choose ember when you want to access the automated and in-built tools of Ember to build a highly flexible web app.
- Ember will be the good choice while creating a server-side rendering of HTML codes and add-on features to new or existing ember apps.
- You can go with the ember, if you have to switch the framework of your project without invoking ad-hoc practices.
- If you’re thinking about reducing scoping errors in the web app to create dynamic templates and modules, go with ember framework.
When To Choose Svelte?
- Choose Svelte if you want to build a static web application with rich UI and lean time for development.
- This framework will be the perfect choice to create smaller code bundles to improve all components’ efficiency in the web app with high browser performance.
- While minimizing the compiling error overhead with the ability to manipulate the DOM to build reactive web apps, go with svelte.
- When you want to, extensively re-use components for developing web apps.
